Well, the iSpring folks seem to think that their
SCORM output works with Canvas, but I have not tried that.
If SCORM doesn't work out for you, you should be able to upload the entire iSpring HTML5 folder into Canvas Files and link to it. That works just fine for content delivery, but there won't be any tracking beyond knowing whether students have hit the page, which you can track in a couple of ways. If you make the content a module element, you can require it, and even use it as a basis for selective release of other content.
